Hub, Madairasoar, at iMiiiiuc, Dr. Lyall. /3. Madagascar, Gumlot. — 

 My specimen which I had called />. Emirnemis, MSS. is uiKiueslioiiahly 

 the same species with D. Goudotiana, Kze., and being more compound, it 

 is probably the more fully developed state : hence I have been led to consi- 

 der Knnze's plant as the variety. It is an extremely distinct species and 

 probably very rare. 



88. D. Schlcctoidalilii, Pr. ; frond ample spreading 3 — 4 

 pinnate snbrigid, primary pinn;o spreading or dedexed, secon- 

 dary and pinnules dicliotomonsly divided divaricating dis- 

 tant the segments narrow linear single-veined slightly di- 

 lated npvvards (hence cuneate) grooved on the nnderside, 

 rachis 4-sided and as well as the main rachis everywhere 

 zigzag, sori terminal solitary, involucres broad ovate or obo- 

 vate the apex free forming with the apex of the segment two 

 rounded lips. (Tah. LIV. C.) — Pres/, Tent. Pterid. p. 129

Hab. Mexico, Schiede and Deppe : Slate district, east of Oaxaca, 

 3 — 5000 feet of elevation, Galcotti, (h. 6372). — A sinj^ular, and apparently 

 a somewhat scandent, Fern, copiouslj'and deeply divided into very narrow, 

 divaricating-, rather ri<>fid segments, deep brown in colour. Here the fruc- 

 tification, though tmly that of a Davallia, puts on the appearance of that 

 of an Ili/menophi/llum, so much does the apex of the segment of the 

 frond resemble one of the lips of an involucre, to which the involucre 

 itself is parallel. The segments are as narrow as those of D. Bhimeana 

 (supra, p. 177), but the composition of the frond and the sori are quite 

 different.

Hab. Caracas and Chacao, Humboldt. Panama. {Presl). — With this I 

 am unacquainted : and neither of the authors who have described it 

 alludes to its affinities. Mr. J. Smith considers it may be D. yibhe- 

 rosu, Sw. 



90. D. t /tec if/era, H. B. K. ; " fronds at the apex bi- at 

 the base tripinnate glabrous, pinnules linear-cuneate fur- 

 nished with a rounded sorus beneath the a]iex, involucres 

 entire, rachis alato-marginate." H. B. K. Nov. Gen. Am.
